Internal calls between employees


There are two ways your Bitrix24 employees can call each other using Bitrix24 tools:

  • Via Bitrix24 Messenger Web, Desktop and Mobile app using WebRTC technology.
    Important. Allow (this address is used for calls) access and open port 3478 (TCP and UDP) for STUN and TURN protocols. If peers are not able to establish a direct connection, TURN-server can act as a proxy for RDP connection (UDP ports 16384-32767).

  • By dialing the extension number in Bitrix24 Messenger. Or by dialing on SIP phone the extension number associated with a certain employee.
    Important. When dialing an employee's extension number, the call is made through our Voximplant operator. These calls are NOT charged.
